OSLO, Oct 8 (Reuters) - Norway’s leftwing Labour Party and the rural Centre Party said on Friday they have agreed to form a minority government, the culmination of almost four weeks of negotiations following last month’s election win. The deal paves the way for Labour leader Jonas Gahr Stoere here to become prime minister next week, replacing Conservative Prime Minister Erna Solberg who said after losing the election that she plans to step down.
